文摘The problem of collecting solar energy and increasing its efficiency was studied in this paper. It was discovered that a 3DPV （three-dimensional photovoltaic） structures can generate greater amounts of measured energy densities than stationary flat PV panels （rate： 2 to 20）. It has been found that the same structures work better not only because they are made in 3D but because PV panels do not have linear dependency on geometry. It seems that the conversion efficiency depends on the process of absorption of the solar energy, too, or in other words on the E. Yablonovich limit. The findings suggest that the quantity of material of solar panels may be reduced to generate the same amount of electricity.
